摘要
介绍一套原设计能力为40kt/a的黄金冶炼厂烟气制酸装置的生产实践与改造。装置采用浆式进料,烟气中水分、尘和三氧化硫含量较高,给制酸系统带来很大困难。通过技术改造,采用ⅢⅠ-ⅤⅥⅡ“3+2”两转两吸工艺,制酸系统运行稳定,二氧化硫转化率达99.6％以上,硫酸生产能力达80kt/a,各项技术指标达到设计要求。
The production practice and retrofitting of a sulphuric acid plant based on gold smelter off-gas with an original design capacity of 40 kt/a is described. The high contents of moisture, dust and sulphur trioxide because of slurry feeding had been a challenge to normal operation. By equipment retrofitting and process upgrading toⅢ Ⅰ-ⅤⅥⅡ '3 + 2' configuration, the plant operated smoothly with a convertion of over 99. 6% and production capacity of 80 kt/a and all indexes reached the design targets.
